CVE-2019-25448
📋 TL;DR
OrientDB 3.0.17 contains a stored cross-site scripting vulnerability where authenticated attackers can inject malicious JavaScript by creating users with script payloads in the name field. When other users view the application, the scripts execute in their browser context. This affects all OrientDB deployments running the vulnerable version with user creation enabled.
💻 Affected Systems
- OrientDB
📦 What is this software?
Orientdb by Orientdb
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or deploy ransomware through the application interface.
Likely Case
Session hijacking, credential theft, and unauthorized actions performed in the context of legitimate users.
If Mitigated
Limited impact with proper input validation and output encoding, though some data exposure may still occur.
🎯 Exploit Status
Exploit requires authenticated access but is trivial to execute with valid credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.0.18 and later
Vendor Advisory: https://orientdb.dev/
Restart Required: Yes
Instructions:
1. Backup your database. 2. Download OrientDB 3.0.18 or later from official sources. 3. Stop OrientDB service. 4. Replace the installation with patched version. 5. Restart OrientDB service. 6. Verify functionality.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize user creation parameters
Implement custom middleware to validate/sanitize name parameter before processing
Disable User Creation
allTemporarily disable user creation functionality for non-admin users
Modify OrientDB configuration to restrict user creation to administrators only
🧯 If You Can't Patch
- Implement WAF rules to block POST requests with JavaScript patterns in name parameter
- Enable Content Security Policy headers to restrict script execution
🔍 How to Verify
Check if Vulnerable:
Check OrientDB version: if running 3.0.17, you are vulnerable. Test by attempting to create user with <script>alert('test')</script> in name field.Check Version:
orientdb --version or check server startup logsVerify Fix Applied:
After patching, attempt the same XSS payload in user creation. It should be sanitized or rejected.📡 Detection & Monitoring
Log Indicators:
- POST requests to /document endpoint with script tags in parameters
- User creation logs containing JavaScript patterns
Network Indicators:
- HTTP POST requests with suspicious content in name parameter
- Outbound connections to unknown domains after user creation
SIEM Query:
source="orientdb" AND (method="POST" AND uri="/document" AND (param="*<script>*" OR param="*javascript:*"))
